    摘要: A cleaning agent and a cleaning process for cleaning a harmful gas containing, as a harmful component, an organometallic compound represented by the general formula: Rm—M—Hn wherein R is alkyl; M is As, P, S, Se or Te; and m and n are each positive integer satisfying the relation: m+n=valence of M are described. The cleaning agent contains, as an effective component, copper (II) oxide or a mixture of copper (II) oxide and manganese dioxide. The copper (II) oxide has a BET specific surface area of 10 m2/g or greater which is extremely larger than that of copper (II) oxide conventionally used as the effective component of known cleaning agents. With such an extremely large BET specific surface area, the cleaning agent strongly and stably adsorbs the harmful organometallic compound, thereby efficiently cleaning the harmful gas without causing desorption of the adsorbed organometallic compound.

    摘要: A process for cleaning a harmful gas which comprises bringing a harmful gas containing a halogen gas and/or a halogen compound gas such as hydrogen fluoride, hydrogen chloride, tungsten hexafluoride, silicon tetrafluoride and boron trifluoride into contact with a cleaning agent comprising metal oxides composed principally of copper (II) oxide and manganese (IV) oxide that are spreadingly and adhesively incorporated with sodium formate so as to remove a harmful component from the harmful gas. According to the cleaning process of the present invention, it is possible to remove harmful components from the harmful gas in extremely high efficiency at ordinary temperature, dispensing with heating or cooling irrespective of the concentration of the harmful components. The cleaning capacity of the cleaning agent is favorably maintained without deterioration even when the harmful gas is in a dry state. Furthermore, the cleaning agent can remove the harmful gas in safety without a fear of causing fire or elimination of the harmful component therefrom. The cleaning process is highly useful and significant in that it is well suited for cleaning exhaust gases from a semiconductor manufacturing process as well as an emergency countermeasure against the leakage of harmful gas from a gas cylinder.

    摘要: It is an object of the present invention to prevent recurrence of an overload condition after occurrence of the overload condition, thereby improving operability and safety in a drilling device. A motor 12 for rotating a drill is connected to an AC power source 10 through a motor control unit 28, a current detector 30, and a power switch 36. A magnet 16 is also connected to the AC power source 10 through the power switch 36 and a full-wave rectifier 18. The motor control unit 28 rotationally drives the motor on the basis of a signal sent from a main control unit according to a state in which a motor start switch 38 is on. The main control unit 14 controls the motor control unit 28 to gradually reduce a supply voltage to the motor 12 when the motor 12 becomes overloaded, to gradually increase the voltage to the normal power supply condition when the overload condition is vanished, and to stop power supply to the motor 12 if the overload condition continues for a predetermined period.
